Increase Temperature Of Steam Boilers

Basic Steam Theory - Steam Pressure - iForm

2008-10-21·The temperature of steam at this atmospheric pressure is the same as the temperature of boiling water at atmosperic pressure, which is 100 deg.C. So long as the imaginary spout remains on our boiler, everything is at atmospheric pressure and its specified temperature.

Steam Pressure Reduction: Opportunities and Issues - NREL

2013-9-26·Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boilers net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.

2011-4-7·Calculating the cost of energy at $1.00/100,000 BTU, this seemingly small increase in flue temperature will increase the boiler operating cost by $33.00/day. Over a 2,000 hour heating season, this will increase the operating cost by $5,513, as the boiler will have to cycle longer to meet the heating load.
